Hey guys, I have heard that Ford made Y-block that was near 500 cubic inches? Is this true or not?

Also what is the biggest cubic inch Flathead engine?


I'm just curious, and I thought you guys would know? There is a company out there that is making NEW Flatheads from aluminum. They are supposed to be 100 inches bigger than stock. They haven't gotten them done yet, but they say soon. I'm not sure where I saw it,but it was in a magazine article.

 

While not refered to as such, FE and FT engines are Y blocks.

Largest flathead (T-head) 4 cylinder engine in a passenger car: 866 cid Locomobile engine from around 1910.

The 1949/51 Lincolns and 1948/51 F7 and larger trucks used a 337 cid flathead V8.

Oddball flathead engine: 135 degree 431 cid flathead V16 as used in 1938/40 Cadillac's.

 

The Ford Y block topped at 312 cid.
I havent seen a 534 truck engine in years, cant remember if it featured Y block construction (not the 239-312 family, but the construction)

 

My pea-brain seems to recall an outfit that built a Y-Block for Bonneville a few years ago that was seriously high-tech. Was going to be the fastest Y-Block ever. Anybody recall ?

 

So ND reckon that's the engine they were talkin about in the song" Hot Rod Lincoln"? I didn't know they made such a big Flathead V8? What was the hp on that engine? Any pics? I certainly didn't know that they made such a big 4cyl flathead? COOL

BIGGER is BETTER!!

 

Lincoln had a V12 flattie in the 40's. I don't know how big it was but Chip Foose put one in his P40 inspired highboy he's building for himself.

 

It was 292-305 cid, it had some issues, ring wear, overheating.

 

All the flatheads had overheating problems Arkus Dontov first built the ARDUN OHV conversion heads to help alieviate the overheating in Flatties used in trucks. The early hotrodders soon discovered they flowed better than the F valve arrangement.

 

Ford built a 500 cu in all aluminium V8 Flathead during WWII for tanks. It started life as a V12 for aircraft but the Gubment needed a tank engine.
Every so often one shows up being stuffed in a Falcon or something like that.

 

Very cool info. I love this stuff!

 

Lincoln 1940, V-12 , 414ci, 150 hp also a V-12, 292ci, 120 hp.

Cadillac had a V-16, 1930-1937, 452ci and a V-16, 1938-1940, 431 ci. About 1955 I saw one of these. I remember the extra long hood and the my older friends knew it was a V-16.

Have a great day, chuck

 

Correction to that, you are referring to the GAA motor used in the 1943 M4A3 mid production Sherman tank, the only version of the tank built by Ford and only in 1943. It featured a 75mm howitzer, and what is called wet artillary stowage (shells were stored in a container of liquid to prevent detonation upon impact). The Ford GAA-IIIV-WC is actually a 4-cam Overhead Cam engine, and is not a flathead. It was mated to a truck 5 speed manual transmission that was all installed backwards and the driveline was open, and ran along the floor to the front drive axle that resembles an Eaton big truck differential. Drivers used a clutch and it operated much like driving a commercial rig of that vintage. It had a 300 gallon gasoline capacity and a range of roughly 130 miles o good flat open road. (3 gallons per mile, that sucks). It is also the only model of tank that had provisions for turn signals, brake lights, and head lights. It can even be registered as a motor vehicle in the state of Oregon (I found a loop hole in the law when I was looking to purchase a partially restored Ford built Sherman about 4 years ago). The current market for this tank does have many available for sale (you have to know where to look), and they are fetching any where from $75,000 partially restored, upwards of $150,000+ for a good parade rig. I used to have as much data on the Ford Sherman as ND has on Ford part numbers. remarkable machine, and the motor was an item to marvel at. It produced a very loud and rather tinny tone, surprising for an open exhaust system. If you watch the 1984 James Garner movie Tank, the main tank used is a Ford Sherman. I own the movie, and I love it.

 

None Ford built. M4A1

 

500 gross hp @ 2600 rpm, and 1040 gross lb/ft torque @ 2200 rpm 26mph top road speed.

 

The Ford built M4A3 Mid production 75MM/W Sherman with Ford GAA-III and synchromesh 5 speed. 18 liters, or 1,100 cid, 500 hp, 1000lb ft torque. To correct my previous post....The transmission is mounted to the front diff, not the engine. The clutch is still on the motor though, and the drive line runs open along the bottom of the hull.
